As Dallas’ disappointing season winds down, they made a few roster moves Tuesday. The team has placed linebacker Leighton Vander Esch and guard Xavier Su’a-Filo on injured reserve, while signing linebacker Ray-Ray Armstrong and offensive tackle Wyatt Miller to the active roster to take their places.

We heard yesterday that Vander Esch would undergo season-ending neck surgery, so this move was just a formality for him. Su’a-Filo had been starting at guard for the past month, meaning the Cowboys will be making an offensive line change for their Week 17 date with the Redskins. Dallas can still sneak into the playoffs as the NFC East champ, but they’ll need the Eagles to lose to the Giants for that to happen. Su’a-Filo was the 33rd overall pick of the 2014 draft by the Texans. He started for a while in Houston, but was mostly a disappointment.

He came to the Cowboys early on last season on a two-year deal, and ended up starting eight games. He’ll be an unrestricted free agent this spring. Armstrong is a journeyman who has bounced around the league a lot over the past handful of years, appearing in five games for the Saints earlier this season. Miller is a rookie UDFA from UCF who had been on the Bengals’ practice squad.
